If you are an NDIS provider, you may already know that many supports and services are GST-free. But, you cannot simply assume all invoices will qualify. The ATO requires clear and accurate invoices to support GST-free claims. 


Without proper documentation, you risk losing the GST-free status I there is a ATO audit, which could result in unexpected GST liabilities. Many providers don’t know that a simple invoice isn’t enough and that it needs to clearly shows the right details to qualify for the GST-free status.  


What Makes an Invoice “Clear”? 

1. Essential Information - A valid GST-free invoice should include: 

  • The words “GST-free supply” clearly stated 

  • The provider’s ABN 

  • The date of issue 

  • A clear description of the services or supports provided 

  • The total price charged 


2. Why Clarity Matters 

Ambiguous invoices can raise red flags. If your invoices do not clearly outline why the supply is GST-free, you may not be able to support your claim in case of an audit. This can lead to the ATO rejecting your GST-free treatment and forcing you to pay GST on past supplies. 

 

3. Common Mistakes Providers Make 

  • Forgetting to note “GST-free supply” on invoices 

  • Using vague service descriptions that do not match NDIS categories 

  • Mixing taxable and GST-free items in one line without separating them 

  • Not keeping copies of invoices for their records 


4. Best Practices for NDIS Providers 

  • Use accounting software that automatically labels GST-free items 

  • Train your staff to issue invoices correctly every time 

  • Review invoices regularly to ensure accuracy 

  • Keep digital and physical records for at least five years 


Do’s and Don’ts 

Do 

  • State “GST-free supply” on your invoices when applicable 

  • Provide detailed service descriptions 

  • Keep copies of all invoices securely stored 

Don’t 

  • Leave invoices vague or incomplete 

  • Assume all NDIS services are GST-free without checking 

  • Wait until an audit to realise your invoices are not compliant 


Insights From Our Experience

Once they set up proper invoicing systems, they not only reduced compliance stress but also felt confident that their GST-free claims would stand up under review.
